This time regarding my M-H 744D tractor. The catch for the brake pedals is:
a) so small
b) so inaccessible. Impossible to bend down and reach it by hand as the steering wheel stops you bending forward.

I've found there are two solutions - always carry a stick with you to press it down when necessary, or, if you forget your stick then hold the brakes down with your right foot, drag your left foot over to replace it and then push the catch down woth your freed right foot.

Am I missing something???? What are the 44s like over there in this respect?

I attach a photo - the catch is just about visible between the two brake pedals
